METHOD OF DOUBLE-STAGE FUEL BURNING AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2008 - IPC F23B60/00 F24H1/24 

FIELD: heating.

SUBSTANCE: method of double-stage fuel burning includes the first stage of solid fuel burning that provides gas generation and the second stage of generated gas burning. By loading fuel through loading hatch, which is equipped with device for sector loading, cone is shaped from supplied fuel, the centre of which is displaced relative to the centre of combustion chamber base, which provides separation of combustion chamber into two burning zones and combination of dense high temperature flame, which is created in the process of fuel layer burning at the cone base, with gases that are created in the process of fuel burning in the whole height of cone, and burning process intensification is carried out by bore piercing of the whole solid fuel burning zone with the help of vertical rods that are lowered from the top part of boiler plant, and forced air supply into cindery part of furnace.

EFFECT: invention allows to create environmentally safe smoke-free method of solid fuel burning with high coefficient of heat generation and heat emission with the help of boiler plant of double-stage type.
